Measurement of Neutrino-Electron Elastic Scattering at NOvA Near Detector

The NOvA experiment is a long-baseline neutrino oscillation experiment designed to measure muon neutrino to electron neutrino oscillation. It uses the NuMI beam at Fermilab and consists of a far detector in Ash River, Minnesota and a near detector at Fermilab. An accurate prediction of the neutrino flux is important to both oscillation and cross-section studies at NOvA. Neutrino-electron elastic scattering is a pure leptonic process with well-known cross section. It provides an in situ constraint on the absolute flux. This poster discusses the measurement of neutrino-electron elastic scattering and the constraining of neutrino flux at the NOvA Near Detector.
